a basic ACPI SLIT table parser.
For now this just exports the map via sysctl; it'll eventually be useful
to userland when there's more useful NUMA support in -HEAD.
* Add an optional mem_locality map;
* add a mapping function taking from/to domain and returning the
relative cost, or -1 if it's not available;
* Add a very basic SLIT parser to x86 ACPI.

Offet for the power control register was specified incorrectly (it had

the offset value to 0xF80, per the ARM PL310 documentation.

The function clearning credentials on failure asserts the process is a
zombie, which is not true when fork fails.
Changing creds to NULL is unnecessary, but is still being done for

building arm images. This is similar to tools/vmimage.subr
used for building virtual machine disk images. By default,
only arm_create_disk() and arm_install_base() contain real
functionality here, and arm_install_uboot() must be overridden
in the arm/KERNEL.conf file.
In release.sh, make create_arm_armv6_build_release() do
something now.
In arm/BEAGLEBONE.conf, set IMAGE_SIZE, PART_SCHEME, FAT_SIZE,
FAT_TYPE, and MD_ARGS, as well as make arm_install_uboot()

Parts of this were taken from disecting a previous BEAGLEBONE
image, and other parts obtained from Crochet sources.
